Nepal Landslide Blocks Chaulani River, Flash Flood Warning Issued in Darchula
A massive landslide in Nepal’s Darchula district has partially blocked the Chaulani River, prompting flood warnings as authorities fear further landslides could trigger a sudden breach and flash floods downstream.
The landslide struck Bhattar in Api Himal Rural Municipality, sending a large volume of debris into the Chaulani River and disrupting its flow. The District Administration Office in Darchula warned that further landslides could completely block the river, potentially causing a sudden breach and flash flooding in downstream areas.
Residents living along the riverbanks have been urged to remain alert and take necessary precautions. Security personnel have been deployed to inform people in vulnerable areas and remain prepared to respond if an emergency occurs.
Sudurpaschim Chief Minister Khagraj Bhatta has instructed local authorities and security agencies to remain on high alert and make preparations for any possible emergency. The administration has also released emergency contact numbers for flood and disaster-related assistance.

The Armed Police Force said the Chaulani River was currently flowing at a normal level. However, personnel from the Nepal Chameliya Hydropower Security Base in Balanch have been mobilised to monitor the situation and warn nearby communities if required.
The latest warning comes as Nepal continues to deal with the aftermath of severe flooding and flash floods in several areas. Rescue and recovery operations remain underway after recent floods displaced communities and resulted in deaths and widespread damage.
The partial blockage of the Chaulani River has heightened concerns that additional heavy rainfall could further destabilise the situation and trigger another flash-flood emergency downstream
